Nomination as UNESCO World Heritage Site

The Dutch government has now joined two German federal states in nominating the Rhine border as a World Heritage site. Austria will do the same for the Danube border. If accepted by UNESCO, an uninterrupted stretch will be a World Heritage Site in 2021.

The so-called Hanseong Baekje [extension] will likely be delayed since its currently waiting approval to be added to Korea's tentative list and a fair amount of archaeological work is still being done.

With the failure of Hanyangdoseong in 2017, it is already being planned for resubmission in time for the 2020 WHC. I have no reason to believe Gaya will maintain its slot, as the same thing happened with the Seowon nomination after a Deferral.
